I am searching for a study guide, as described in the question, giving comprehensive primary sources (e.g. ideally stating all discovered theogonies) and discussing each primary source.
It would be helpful if such a study guide gives the details of multiple (ideally all) versions of the myth (if there are multiple versions). It would also be helpful if the study guide put the works in internal chronology as well, e.g. Cypria before Iliad.
Thank you
There are literally hundreds of books on the topic, but the best one for serious work is Timothy Gantz's Early Greek Myth. This book goes through the earliest sources for the myths and chronicles their development over time. He even covers artistic representations.
I would not necessarily call it an "introduction," as it is a proper academic resource, but if you want to get to the original sources fast, this is your best bet.
Incidentally, the book is somewhat internally chronological, i.e. Perseus is covered before Heracles' labors, but the chapters will cover lineages as a whole, so if you read it front-to-back (instead of using it as a source book), you'll read about the Seven Against Thebes before reading about Tantalus. There are excellent genealogical tables in the back though to help guide you to what came first.
